SPECIFICATION forming part of Letters Patent No. 413,849, dated October 29, 1889. Application'led January 30, 1889. Serial-No.298,092. (No model.) Patented in Canada December 27, 1888, No. 30,500.

`To all, whom it may concern: f

Be it known that I, WILLIAM DRIscoLL, a `subject ofthe Queenof Great Britain, resid` ing at Brockville, in the county of Leeds and `1 5` Province of Ontario, Canada, have invented I a new and useful Improvement in Window- Y Sash Supports, (patented in Canada under 1 No. 30,500, datedDecember 27, 1888,) of which the following is a specification.

My invention relates to improvements in `window-sash supports; and it'consists in certain novel featuresfhereinafter described and claimed.

In the accompanying drawings, Figure l is an elevation-of the window-frame, a portion of the sash being shown in section. Fig. 2 is a sectional view on the line of Fig. 1, and

Fig. 3 is ay detail view of the device for lock` ing the sash. Fig. 4 is a detail view of the 2o screw and its attached parts. y

Referring .to the drawings, A designates4 through the slot G into the window-frame andsecuredtherein.l This screw is provided `at an intermediate portion of its length with `the lateral wingsJ, which are beveled 011 their front and real-'edges and also on'their side `faces toward their upper and lower ends, as ,clearly shown. These ,wingsiit in the slot of the sash-supporter and lthereby maintain the same in a true verticalposition within the groove of the window-frame. A thumbend ofv thescrew and adapted to bear against `the outerface ofthe sash-supporter, so as to clamp the same in itsadjusted position.

In practice the sash is adjusted to the desired height, and the lever or butt-on E is then nut K and washer L are mounted on the front turned, so as to engage one of the recesses or spckets C in the window-frame, and thereby support the sash while the supporter is being secured in position. The sash-supporter is then moved along the grooves, so that its upper end Willbear against the lower edge of the sash, and the thumb-nut is then turned up, so as to force the washer home against the face of the sash-supporter and thereby secure the same firmly in its adjusted position. The beveled construction of the lateral wings of the screw I permits the said screw to be turned home without causing the said wings to scratch the face of the windowframe, and also permit the washers tobe driven positively and squarely against the sash-supporter. The device is very simple and can be quickly and easily-operated. The button or lever is so shaped at its ends that when it is in the position shown in full lines in Fig. 3 the sash can beneither raised nor lowered vwithout iirst disengaging the lever or button from the recess in thel windowframe, and, as access cannot be had to the button from the outside, it is obvious thatv the button forms a burglar-proof fastening. When the button is in the position shown in dotted lines in Fig. 3, the sash cannot be lowered, but upon being raised will draw the button out of engagement with the recess in the window-frame.

Having thus described my invention, what I. claim, and desire to secure by Letters Patent,

1. A sash-supporter comprising a plate secured tov the window-frame below the sash and adapted to bear against the lower edge of Athe sash-and adjustable vertically along the window-frame, as set forth.

2. A sash-supporter comprising a longitudinally-slotted plate arranged adjacent to .the window-frame below the sash, the screw passing through the slot in the plate and secured in the window-frame, and the thumbnut mounted ond the screw and bearing against the outer side of the plate, as set forth.

3. f `A sash-supporter comprising a longitudinally-slotted plate arranged below the Sash and adjacent to the Window-frame, the In testimony that I claim the foregoing as screw passing through the slot in the plate my own I have hereto afxed my signature in and into the window-frame and .having Iatpresence of two Witnesses. eral wings tting'in the slot in the plate, and WILLIAM DRISCOLL.

5 the thumb-nut mounted 0n the screw and bearing against the outer side of the plate,

Witnesses:

EDMUND F. BURRITT,

as set forth. l D. J. HURTEAU.
